Gamo PBA Raptor Ammo .177 Item Number: 632264454 The Raptor Performance Ballistic Alloy, the first non-lead Alloy Airgun Ammunition that increases velocity up to 25% over lead, while maintaining match grade accuracy. Specifically designed as a hunting load, the new P.B.A. enables airguns which normally shoot 1000 f.p.s. to shoot up to 1200 f.p.s., with tremendous penetration. In fact, the ammunition is 50% harder than lead causing penetration to be enhanced by up to 100% in tests in actual hunting situations as well as ballistic mediums. Raptor P.B.A. test results show ballistic stability at super-sonic speeds and up to 90% weight retention using the new semi-pointed design. Comes in a 100 count .177cal rocket package.
